Title: Charge-state detector for battery charger - has voltage and current detectors allowing independent charging
Inventor: OKUNO KENO
IPC: G01R15/00
Filed: 1975-03-20
Abstract: The charge-state detector, for a battery charger with high initial charging currents, has a combined voltage detector and current control circuit to determine when the battery terminal voltage reaches a given level and then to reduce the charging current. A current detector circuit determines when the battery charging current has reached a given value and then initiates the generation of a 'charging complete' signal which operates some form of indicator. The complete detector circuit eliminates the effect variations in ambient temperature have on the charging process and allows the battery to be charged fully in all temperature conditions.

Title: Lathe with non rotating cutter - has cutter mounted on oscillating tool holder to vary radial distance into work
Inventor: BERTIN ANDRE
IPC: B23Q1/54

Abstract: The cutting tool is mounted on a tool holder which can rock to and fro about the shaft on which it is mounted. The shaft itself is mounted in a second rocking part and carries a cam which engages with a fixed surface, so that while the cutting tool is moved to and from the workpiece, it is also moved up and down. The radial distance from the point of contact of the cutter with the workpiece to the centreline of the workpiece will therefore be varied over a fixed cycle. Alternatively, the cutter mount is being moved to and fro.

Title: Hexahydro-6-methoxy-11-methyl-iminoethanophenanthrene salts - birth control agent for males by delaying ejaculation
Inventor: SPAIN LEVERN
IPC: A61K31/445
Filed: 1975-09-02
Abstract: The human male's ability to ejaculate is diminished by administering to the male a 0.06-0.725 g. dose of an acid-addn. salt of d- 1,3,4,9,10,10a-hexahydro-6-methoxy-11-methyl-2H, 10, 4a- iminoethanophenanthrene (I). Cpd. (I) is used as a birth control agent. The ability of a male to ejaculate can be delayed or even prevented for about 15 hours depending on the dose level. Also the amount of semen and living sperm ejaculated is greatly reduced, so minimising the possibility of fertilising the ovum. With increasing dosage of (I) there is also an increasing delay towards the point of ejaculation during physical stimulation, e.g. with 0.08-0 2g. the delay is from 15-30 mins. from initial stimulation.

Title: Crack depth measurement for metallic workpieces - uses AC of frequency adjustable for different workpiece materials
Inventor: GILLE GERHARD DR ING
IPC: G01B7/26
Filed: 1976-01-09
Abstract: A method is used for determining the depth of cracks in metal work pieces of different material by passing alternating electrical currents through the piece perpendicular to the cracks (3) and measuring the voltage between two surface points. It is designed so that the same function between current, crack depth, and voltage applies to all materials. For each material the frequency of the alternating current is so adjusted as to produce the same voltage in a crack free region of the material as is produced in a sample workpiece of given material. The method also employs a compensation voltage applied to the current circuit so as to oppose induction voltages.

Abstract: Continuously rotating sleeve valve for a 4-stroke IC engine has a wormwheel fixed around its base by circlips. A worm driven from the crankshaft meshes with this wheel and rotates the sleeve at 1/4 crank speed. At the top, the outside surface of the sleeve is conical and makes a gastight sliding joint with a corresponding surface in the cylinder head under press. from an annular flat spring backing the thrust race on which the sleeve runs. In this part of the sleeve there are two diametrically opposed ports. In combination with pairs of inlet and outlet ports, also diametrically opposed, in the cylinder these act as valves to control the cyclic gas flow. The flow is guided by grooves in an insert in the cylinder head, projecting inside the sleeve. The thrust race has a separate lubricant supply, and return.
